The Holy spirit has an important role, to play in our lifes because, the greatest thing that God has done for us is to give us the holyspirit. It is for him to pour out the holy spirit upon us and make it possible in our day, to have the holy spirit in our lives. The Holy spirit is the almighty spirit of God, his the one who communicates the presence of God, and so many christians have never known the importance of that, that's actually what made jesus the christ.
The Holy spirit is the third person of the trinity, revealed to the christian. He is one with the father and the son. He is neither less important or less powerful, He is God, and co equal with the father son and the holyspirit.
Right from the beginning of the Biblical scriptures, we are introduced to the person pf the Holyapirit, and throughout the scriptures, we re further acwuainted with him, His power and his person. In all this his ministry is clearly revealed not to exault Himself, but to lead us and reveal to us the person of jesus.
Food for thought, inspirational.
